AX5505  MICROPOWER  VFM SYNCHRO*US STEP-UP DC/DC Converter

性能描述：

    The AX5505 is a high efficiency VFM synchronous Step-up DC/DC converter for *all, low input voltage or battery powered systems with ultra-low quiescent supply current. The AX5505 accept a positive input voltage from start-up voltage to VOUTand convert it to a higher output voltage in the 2.1V to 5.0V range. 
     The AX5505 combine ultra-low quiescent  supply current and high efficiency to give
maximum battery life.Thehigh switching frequency and the internally limited peak inductor
current permits the use of *all, low cost inductors. Only three external components  are needed an inductor a diode and an output capacitor. 
     The AX5505 is suitable to be used in battery powered equipment where low noise, low ripple and ultra-low supply current are required. Operating shutdown function is outside
controlling. If EN connects to GND, the IC was been shut down and then the supply current
is lower to 1uA.The AX5505 is available in very *all packages: SOT23-3L, SOT23-5L and
SOT89-3L.
     T*ical applications are pagers, cameras and video camera, cellular ephones,wireless  ephones, palm* computer, battery backup supplies, battery poweredequipment.

特点：

• Very Low Supply Current is 13uA (t*.)
• Maximum shutdown current <1uA
• Output voltage is available form 2.1V to 5.0V by 0.1V steps
• Output Voltage Accuracy &plu*n;2%
• No Schottky Diode Required
• Output Current up to 100mA
• Low ripple and low noise
• Very low start-up voltage at 0.8V
• Few external components
• Low profile: SOT23-3L, SOT23-5L and SOT89-3L Pb-Free
